Abstract

The invention provides a method for detecting visible foreign matters in medical agents based on affinity propagation cluster. The method comprises the following steps: acquiring a sequential frame liquid medicine image; filtering the sequential frame liquid medicine image to acquire a background difference image by utilizing the boundary-protecting and noise filtering properties of a two-sided filter; performing spatial median filtering on the acquired background difference image so as to eliminate the noise; segmenting and extracting a connected domain target and characteristics thereof in the background difference image subjected to the spatial median filtering; classifying the extracted connected domain target by using an affinity propagation clustering algorithm; and analyzing a path form of the target according to the classification result, judging the class of the target and judging whether foreign matters exist according to the classification result. The precision and the speed of medicine detection are greatly improved, the method has high practical value, the related technology can be popularized and applied to the quality detection field of foods and drinks, the demands are wide, and the economical and social benefits are obvious.

Description

technical field [0001] The invention belongs to the field of detection methods for visible foreign objects, in particular to a detection method for visible foreign objects in medical medicaments based on neighbor propagation clustering. Background technique [0002] Liquid medicine is a medicine that medical institutions must use daily, and it is also an indispensable carrier or lysozyme for clinical rescue medicine and intravenous treatment medicine, and occupies a very important position in modern clinical practice. In my country, transparent pharmaceutical products that account for more than 90% of the national market are still packaged in glass bottles. Due to the production process and packaging technology, transparent pharmaceutical products may contain tiny insoluble foreign matter such as glass chips, rubber chips, and fibers. These insoluble foreign bodies from different sources often carry a huge number of bacterial microorganisms, resulting in serious contaminati...
